200C ain't that hot either, the stock pads should do that easily so how are you measuring? Also bad rear pads might be so low friction they put you outside the range of adjustment for the EBD. Until I put matching race pads front/rear my fronts got much hotter.


Stock Mazda pads all round. Temps measured using an eBay infra-red thingo. Not the most exact thing in he world but near enough. They didn't overheat. They just wore out. And never having dríven a car so hard before, and never having worn pads out, I didn't recognise the symptoms until the left front was metal to metal.

I hear what you're saying about a prop valve and won't go there. I also noticed that drivers around me (more often in front of me) are blipping the throttle and changing down while braking whereas I get the braking done then change down one or more gears as needed. Doing what the others do will make the rears do a bit more work but I'm told I need to watch out for overcoming the ABS and EBD and locking up the rears when I do this.

On goes the learning curve. And on go slotted rotors and better pads.

Most times you should be changing down while you are braking, (unless you wont need to change gear) so you can ensure you are in the right gear to exit the corner.
(downchanging is not to help with slowing down either. The brakes are for slowing down, gears are for accelerating. )

The idea being once you've finished braking and come off the brakes and back on the throttle you will be in the right gear to then accelerate out of the corner.

Blipping the throttle to rev match on downchanges, (heel and toeing) reduces the chances of compression lockups, which can unsettle the car, as well as being nicer on the box..

You're welcome to jump in with me next meet (PI in June) and I can show you what I mean..

When I was doing track days, I was up against 2 other drivers, with the same model year car as me, and we were doing lap times within 0.2 seconds of each other.

One was down to bare metal on his brake pads in 9000km, the other guy's brakes and mine lasted till 30000km. Driver 1 was overbraking.

I over brake. Then go gently round the corner. Then use the horsepower to catch up. Then over brake again. Be patient with me please, especially if I've overtaken you and then appear to just stop. It's not really my fault, just my lack of ability.
